How to solve ipad 3 wifi issue
If your new iPad 3 has poor wi-fi reception, you’re not alone. After getting a shiny new iPad 3rd gen, I immediately noticed it wasn’t registering any bars of wireless reception, and wi-fi was strangely slow regardless of the network I joined or the distance to the router. It must be defective and I should storm down to the Apple Store and get a refund, right? Wrong. It’s actually really easy to fix, so before you call AppleCare support, give this fix a try, it worked for me.
Open Settings and tap on “General”
Tap “Network” and tap “Wi-Fi”
Tap the blue arrow next to the wireless router you are connected to
At the next screen, tap “Forget this Network”
Go back to Wi-Fi and rejoin the network you just forgot
Like magic, you should now have full reception bars, as visible in the upper left wifi indicator.
If wi-fi is still not working, try this as well:
From Settings, tap “General” then “Reset”
Tap “Reset Network Settings”
Reboot the iPad
Connect to a wireless network again
Resetting network preferences loses router passwords, be sure to have those handy beforehand.
Often these issues are software related and fairly easy to handle, as I’ve resolved a number of times with OS X Lion too, so don’t assume some of the complaints you’ll read on Gizmodo and Apple Discussions are all hardware related. That said, if you’ve attempted both of the methods outlined above and your 3rd gen iPad wi-fi is still problematic, you might actually have a genuine problem and it would be worth contacting Apple or AppleCare.
